Table 5.

Pollen germination rate on each anther of the four rice varieties under the two weather scenarios.

Variety	Pollen germination rate (%)
	LHS	NWS
Mianhui101	36.7 ± 5.0b**	42.1 ± 5.4c
IR64	37.2 ± 5.0b**	50.0 ± 6.9b
Quanliangyou681	51.4 ± 7.5a*	57.0 ± 4.1a
SDWG005	37.5 ± 4.9b	41.8 ± 15.2c

** and * indicate significant differences at P<0.01 and P<0.05, respectively, between a variety in the long-term heat scenario (LHS) and the same variety under the normal weather scenario (NWS).

Different lowercase letters indicate significant differences between varieties under the same weather scenario at the 5% level using Tukey’s test (n=20).
